The Redmi Watch 3 in short

  • Rated for 12 days of use per charge.
  • Water rated to 50 m.
  • 10.94mm thick. Thinner than 71% of 37mm watches, so it slides under a cuff more easily than most of its size.
  • 1.75 inches OLED/AMOLED display, always-on capable.
  • Takes 22mm bands, so third-party straps fit without an adapter.

Does the Redmi Watch 3 fit your wrist?

Watch Fit Tool

For sports watches, lug-to-lug (L2L) is what matters most — it decides whether a watch overhangs your wrist. Bulky is fine; overhang is not.

Balanced Fit

42.6mm on a 55mm wrist

10:09TUE 12lug to lug 42.6mmyour wrist 55.0mm

Comfortably inside the edges of your wrist, and it seats and sits low enough to wear without thinking about it.

On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 42.6mm, so you could go bigger.

How to Measure

Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.

  1. 1. Flat width — arm flat on a table, palm up. Measure straight across the top of the wrist, bone to bone, ignoring the curve down the sides.
  2. 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.

Is the Xiaomi Redmi Watch 3 thick for a 37mm watch?

At 10.94mm, thinner than 71% of 37mm watches, so it slides under a cuff more easily than most of its size. Thickness, not case width, is what decides whether a watch catches on a shirt cuff.

Zenith Defy A3643 Revival, Omega Museum Collection Seamaster Milano Cortina 2026 Winter Olympics, Kieslect Ks2, Noise ColorFit Icon 3 all sit within half a millimetre of the Xiaomi Redmi Watch 3's 36.6mm case, so they cover the same amount of wrist.

What is the lug-to-lug of the Xiaomi Redmi Watch 3?

42.6mm, against a 36.6mm case width. Lug-to-lug is the measurement that decides overhang: if it exceeds the flat width of your wrist, the lugs sit past the edge no matter how modest the case diameter looks.
